AI agents call get_instagram_post to retrieve information from Scavio without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves publicly available Instagram post data without creating, modifying, deleting, or executing any operations. It is a pure data retrieval function with no side effects. The blast radius is minimal as it can only fetch existing public information.
From the tool's definition Tool retrieves a single Instagram post including caption, author, media URLs, and engagement stats. The verb 'Get' combined with the explicit description of data retrieval with 'no modification' intent indicates read-only access.
